CRUSHNG AND GRlNDlNG MILL..

SPECIFICATION forming part of Letters Patent No. 359,588, dated March l5, 1887.

Application led November 16, 1895. Serial No. 182,953. (No model).

To alla/hom it may concern: .f

`Be it known that I, JAMES F. WINCHELL, a citizen ot' the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvementsin'Crnshing and GrindingMills, of which the following is a specification, reference being-had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in crushing and grinding mills for reducing corn-cobs, roots, bark, bones, and the like substances, first, .to a broken state, and, secondly, to a granular or iiner state.

In the accompanying drawings, forming a part of this specification, and on which similarletters of reference indicate the same or corresponding features, Figure 1 represents a vertical sectional view of a mill of the character forming the subject of an application already led by me, to which reference will hereinafter be made, showing my present improve-` ment applied thereto; Fig. 2, a plan view of the crushers mounted in theupper portion of the casing, the latter being in horizontal section; Fig. 3, a transverse sectional view ofthe conveyer and of a part of the upper portion of the casing, and Figl a transverse sectional view ofthe conveyer, of the crushing-chamber, and of apartof the upper portion ofthe casing.

The machine illustrated in Fig. 1 is vconstructed substantially in accordance with the machine forming the subj ect-matter of Letters Patent granted to me May 18, 1886, No. 312,311, and May 18,1886, No. 342,158,forin1 provcnients in crushing and grinding mills.

The letter A designates thel main shaft of the machine, on which is rigidly mounted a roller or cylinder, B, constructed with asuitable conveyor, ange, or worm, C, for the purpose of feeding the crushed material to the grindingheads D, which receive and act upon it in the manner disclosed in the patents above alluded to.

The chamber in which the conveyor works is provided with longitudinal ribs B', and the distance between the periphery of the conveyer and the sides of the chamber, as seen in Fig. 4., is greater than the distance between the said periphery and the said ribs. rlhe result of this construction isto canse the material to feed more rapidly to the couveyer, while the presence of said ribs enables the conveyer to further reduce oncrush the material before it reaches the grinders proper.

It frequently happens that lumps too large to go directly to the grinders escape the upper crushers; but this further crushing action of the conveyer and ribbed chamber brings all the material to a proper size.

The hopper and the flap alluded to in my said patents are also preferably employed in connection with the present crusher and the hopper mounted upon the upper portion of the casing. Y

In suitable bearings, F and G, in the upper portion of the casing of the machine, I mount two crushers, I, side by side, each having crushing protuberances J. rIhe crushers are sufficiently near to each other to cause the crushing protnberances ofthe respective crushers to stand either in line with each other, as seen in Fig. 2, or to lap eachother, or to not `quite reach each other.

rIhe shafts of the crushers are provided with pinions N, which mesh with each other, and

are preferably of the same diameter, while the shaft of one of the crushers is additionally provided with a gear-wheel, K, whereby rotary motion is imparted to both crushers by a pinion, E, which meshes with the gear-wheel K.V The use of two crushers is especially intended for breaking up or crushing cottonseed-meal cakes, though it is found that the two crushers are not in any sense limited in their usefulness to acting upon cotton-seedmeal cakes, since they effect the reduction of bones, bark, root-s, Ste., with equal facility.

I would here observe that I have in view the, combining of two crushers with a moving conveyer (as distinguished from a mere incline) and suitable grinders.

'Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a mill, the combination, with a main` shaft and grinders and a moving conveyer, of a plurality of intergeared crushers mounted to crush the material for the conveyor and having protuberanees which extend approximately in line with each other, one of said crushers being geared with the main shaft.

IOO

2. In a mill, the combination, with the main shaft and the grinders, the moving eonveyer, and a pinion mounted upon the main shaft,

intergeared Crushers mounted above the oonveyer and having protnbelances which extend of approximately in line with each other, one of 15 two intergeared Crushers mounted above the said Crushers having a gear-wheel which conveyor and having protnberanees which extend approximately in line with each other, one of said Crushers having a gear-Wheel which meshes with the said pinion.

3. In a mill, the combination, with the main Sha t', the g1'indingl1eads,the moving eonveyer, and the pinion, the eonveyer and one of the heads being mounted upon the shaft, of two meshes with said pinion.

In testimony whereof I aflx my signature in presence of two witnesses.
